Patent JP-S5642741-A (JP)
Title: Hollow stabilizer for vehicle
Inventor: OONO AKIRA
IPC: B60G21/04
Filed: 1979-09-18
Abstract: PURPOSE:To provide excellent mechanical strength and the optimum low weight generation rate by establishing a specific relation between the inner and outer diameters of the subject stabilizer made of a hollow pipe. CONSTITUTION:A hollow stabilizer consists of a hollow pipe having a torsion part 1 connected to the body of a car in the middle. On the ends of the tortion part 1 are provided arms 3 which are elongated in one piece construction and connected to the wheel sides through bended portions 2. If d1 stands for the outside diameter, and d2 represents the inside diameter of the hollow pipe, the conventional twisted spring constant must be adopted not to decrease the rigidity with the conventional round bar type stabilizer. Therefore, the relation d0<4>=d1<4>-d2<4> is obtained by making the deflexion angle of the hollow pipe member equal to that of the round bar member, if the diameter of the round bar member is defined as d0. Since 10-40mm. are usually adopted for the value of d0, the equation 10<4=d0<4=40<4> is applied. 0.16<=(d1-d2)/2d1<=0.25 is obtained with further considerations for producing lightweight.

Title: Brushless synchronous motor
Inventor: OZAWA KOUJI
IPC: H02P1/50
Filed: 1980-09-01
Abstract: PURPOSE:To reduce pulsating torque at starting by connecting a thyristor in parallel with the rotary field coil of a synchronous motor. CONSTITUTION:When the positive half cycle of the induction field current generated in a rotary field coil 2 at the time of starting a synchronous motor appears at a terminal J, a firing signal is supplied to a thyristor 8 through a transformer 7, a diode 10, and a Zener diode 9 and the induction field current is short-circuited through the thyristor 8. When the positive half cycle appears at a terminal K, the induction field current is short-circuited through a rotary silicon rectifier 4. As this method eliminates most of the DC portions of the induction field current at the time of starting, the occurrence of pulsating torque can be reduced.

Title: Operating method of hydraulic or pump turbine
Inventor: OGIWARA MASASHIGE
IPC: F03B15/04
Filed: 1980-09-01
Abstract: PURPOSE: To improve the operating efficiency of electric power system by a method wherein a generator or dynamotor directly coupled to the turbine is disconnected from the power system at the specified set value of turbine characteristics at the time of changing-over from phase modifying running to power generating running.  
     CONSTITUTION: When the command to change-over from the phase modifying running to the power generating running is issued, the difference ΔP between the input amount P p  corresponding to the settling of the turbine detected with a settling detecting device H and the required output P r  of the electric power system is detected with an input-output operating unit ΔP. If the difference ΔP exceeds the allowable value P, the disconnecting operation of the generator from the power system is performed and, if not, the non-disconnecting operation is performed. In other words, when the operating unit detects that the difference ΔP exceeds the value P, a circuit breaker 52 is opened, 20DG guide vane leakage water discharge valve 6 is closed and a 20AW exhaust valve 5 is opened to discharge from within a draft pipe (not shown) and a runner (not shown). After that, a turbine starting condition detector 65 is turned ON and the turbine is raised its speed up to near the synchronous speed with an automatic synchronizer SS and, at the time when the voltages and the like are nearly synchronized, the circuit breaker 52 is thrown in.

Title: Light emitting element driving circuit
Inventor: TOKUDA RIYUUJI
IPC: G03B3/00
Filed: 1978-10-02
Abstract: PURPOSE: To obtain the light emitting element driving circuit of high efficiency and high accuracy by letting the control signal exciting a light emitting element be the modulated wave signal by pulses, etc. and keeping the input level to an amplifier always within an active input voltage range.  
     CONSTITUTION: Output of a modulating transistor TR 11 is being applied to the inversion input terminal of an operational amplifier 2 together with a reference voltage 1. Power source is being supplied from the common terminal 9. The output potential of the amplifier 2 can be only the low voltage for the voltage between emitter and base of a driving TR 4 even when current flows in a light emitting element 3. This makes operation possible until the supply voltage becomes the value adding the collector-emitter saturated voltage of the TR 4 to the forward voltage of the element 3. In addition, since the control signal such as pulses, etc. is being applied to the input of the amplifier 2, the amplifier 2 may be controlled always in the active region without interrupting the feedback loop. This enables the element driving of high efficiency and high accuracy to be performed.
